An astronaut wandering the solar system encounters a 726 kg steel block resting on a surface where (meau) s = 0.650 and k = 0.400. An attempt by the astronaut to set

the steel block in motion across the surface requires a force of 4930 N. On

which planet is this astronaut wandering? Support your answer with calculations.

Therefore the planet is Saturn .

Explanation:

Let acceleration due to gravity be g .

weight on the planet = 726 g

Frictional force = μs mg

= .65 x 726 x g

This force is equal to 4930 N .

.65 x 726 x g = 4930 N .

g = 10.44 .

Therefore the planet is Saturn .

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

i don't understand. explain it clearly
